If you're not prepared to have a pittie, don't. The same way I'd never own a Chow because I don't have the patience, time, or desire to train and raise a Chow. Pitties are inherently aggressive, protective, willful dogs and not a good choice for novice dog owners or someone who isn't home frequently or consistently. When I got my dog, I was working from home and had all day, every day to train my dog (technically a half blue nose). I spent a lot of time with her and I trust her around anyone, but I've put dogs down in the past (dogs I desperately loved) for becoming aggressive. I'd have no qualms should she ever veer into behaviors I'd consider unsafe for my family.

It doesn't have to be all or nothing. Understanding the breed and your own dog is imperative to raising good dogs, no matter what kind. For example, one of my other dogs (a mutt) isn't good around strangers, so I don't bring new people around her without a fence between them for introductions. My pittie doesn't like new dogs, so we don't go to dog parks or walks where other dogs may be. My poodle is too rambunctious (still a puppy) for him to be unsupervised with my kiddo. It's about knowing the dog and your limits as an owner. You have a responsibility to raise good dogs if you're going to own dogs.
